Question on Train to Bath from Heathrow
 

If anyone can help, I am trying to figure out how to get from Heathrow to Bath after my flight. I am not sure what site I am looking to google for the current trains or tubes from Heathrow. I arrive on Sunday July 16 landing at Terminal 2. Do I take the Heathrow Express to a train somewhere or is there a train to Bath from Heathrow direct? The info I have found was a bit old and I know I will be too tired to make decisions on the fly. Also, do you recommend buying the train tickets now online? Thank you!

There is no train 'from' LHR to Bath. It is either train in to London Paddington or bus to Reading and train to Bath (or some variation of Elizabeth Line towards London and train out to Bath). MUCH easier to simply get on the express coach at LHR and step off in the center of Bath. Take the bus.

Perfect information. Thank you.
